tSPECIFIGATIOLT forming part of Letters Patent No. 709,782, datedSeptember 23, 1902.

Application filed January 2Q, 1902. Serial Na 90,5 71. (N model.)

To (LZZ whom it may concern:

Be it known that I, LOUIS KELLER LEAHY, a citizen of the United States,residing at Los Angeles, in the county of Los Angelcs, State ofCalifornia, have invented new and useful Improvements inHydrocarbon-]3urners, of which the following is a specification.

My invention relates to that class of hydrocarbon-burners designed toburn crude petroleum with steam; and the objects thereof are to producea burner that will burn all grades of crude petroleum and which willregulate the amount of fuel burned automatically by the pressure of thesteam and accomplish other purposes hereinafter explained, and pointedout in the claims.

In the drawings forming a part of this application, Figure 1 is aperspective view of my burner. Fig. 2 is a central vertical section ofthe bu rner-tip and portions of the connectingpipes. Fig. 3 is a plan ofa portion of the tip. Figs. at and 5 are detail views, in centralsection, of different parts, of the regulating device. Figs. 6, 7, 8,and 9 are detail views of different parts of my burner.

In the drawings, Fig. 1, 1 is the oil-supply pipe, which feeds the oilto the burner through the strainer A blow-off pipe 23 connects with thesupply pipe below the strainer. These pipes are provided with cut offvalves l and 5, respectively. The upper end of the blow-off pipe isconnected with the strainer by an improved coupling-joint 6, the detailsof which are shown in Fig. 9. This improved coupling consists ofexternallythreaded sleeve 7, having handle 8, which sleeve encircles thecentral coupling member fl, having shoulder 10, and rotates and slidesthereon when operated. This sleeve screws into the bottom of the casingof strainer 2. (Shown in detail in Fig. 6.) In the top of the casing ofthe strainer-chamber is screwed oil-tube 11, the other end of which isscrewed into aperture 12 in the casing 13 of the valvechamber 14. Thistube connects the strainer with the valve-chamber, which is preferablyof the shape of an hour-glass. In the strainerchamber is the screen 15,through which the oil passes. Surrounding the oil-tube and connectedwith the casing of the valve-chamber and with the casing of thestrainer-chamber is the steam-pipe 16, which forms a heating chamberaround the oiltube. Connected with the casing of the strainer-chamber issteam-pipe 17,which connects with the steamsupply pipe 18, which in turnis connected with the steam-supply. (Not shown.) Exhaust-pipe 19, havingcook thereon to control the amount of exhaust-steam which passestherethrough, is connected with the casing of the strainer-chamber, asshown in Fig. 6. In "alvechamber 14: are revolubly mounted the taperingoil-valve 21 and the hollow tapering steam-valve 22, which areadjustably united by bolt 23, so that they may be rotated together toregulate bya single movement of the regulator, ashereinafter explained,the quantity of steam and oil passing therethrough. The oil-valve isprovided with a transverse channel 24, which registers with the port 25(shown in Fig. 8) in the casing of thevalve-chamberand withalike portinthe opposite side of the said casing opening into the steam blow-outpipe 26, which is connected with pipe 17, so that the oil-passageleading to the burner-tip and the oil-chamber in the tip may be cleanedwith steam. At right angles to channel 24 and opening thereinto is asecond channel 27, which is adapted to connect channel 24 with theoil-tube 11 through port 12. Valve 21 is provided with stem 28, whichprojects through the casing of the valvechamber, to which stem lever 29is rigidly affixed. Steam-valve 22 is provided with a port 30, which isadapted to register and be cut off from register with aninternally-threaded opening 31 in the casingof the valve-chamber, inwhich is screwed pipe 32, the other end of which is connected with pipe17. The internal hollow of the steam-valve is in communication withchamber 14, which chamber is in communication through passage 33 withchamber 3% in that portion of the casing of the valve-chamber whichprojects at right angles to the central line of the steam and oil valvesshown in Figs. 7 and S. Screwed into the end ofthe casing formingchamber 34: is the flanged bushing 35, which provides a bearing-surfacefor the flange 36 of the in ternally-threaded coupling-ring 37, havinghandle 38. This coupling-ring is adapted to be screwed upon the couplingmember 39, which has a central aperture 40 extending therethrough,adapted, when in place, to register with port 25. The details of thecoupling member and the connecting parts are shown in Fig. 8. As showntherein, an oilconduit 41 has one end screwed into aperture tering withpassage 42, are screwed into the casing 43 of the burner-tip, lowerflange 48 being externally threaded for that purpose. Above flange 48 isa second flange 49, which projects beyond flange 48, the two flanges andthe tip-casing forming a steam expansionchamber 50, which is incommunication with the steam conduit-pipe through ports 51 in flange 48and side passage 52 in the tip-casing. On the top of the tip-plug ismounted cap 53, which projects a little beyond and a little below theupper surface of the upper flange of the plug and forms therewithoilchamber 54, which is in communication with passage 47 through ports55. This cap is held in place by nut 56. Flange 49 is provided in itsupper surface with an annular groove 57 for the reception of theoil-supplyregulating ring 58, which is held therein by the cap, and mayhave a portion thereof cut out, as shown in Figs. 2 and 3, to permit theoil to flow out of chamber '54. surface of flange 49 is provided with anannular groove 59 for the reception of the steamregulating ring 60,which is cut out to correspond with the oil-regulating ring, and the tworings are arranged one directly above the other, so as to permit the oilfrom the oilchamber to fall directly upon the steam issuing from thesteam-chamber. The steamregulating ring is held in contact with flange49 by the annular ring 61, which rests on the internally-threaded ring62, which is screwed upon the exterior of the tip-casing and supportsring 61 and holds it firmly in contact with the steam-regulating ring.WVhen it is desired to have a circular flame, the oil and steamregulating rings are removed from the tip. The portion of each which iscut out regulates the size of the flame, and the position in which theyare placed in the tip controls the direction in which the flame isprojected. Portions of these rings may be cut out at different points,and a flame consisting of a number of jets shooting out in differentdirections will be produced. The details of the various partsconstituting the burnertip are illustrated in Figs. 2 and 3.

In the operation of my device oil is fed into the burner through thestrainer, which removes all solid impurities which are too large to passtherethrough. Steam is also fed into The under the burner, and a portionthereof passes into the steam-valve chamber and thence throughconnecting parts to and out of the burner-tip. A portion of the steampasses through pipe 17 into pipe 16 and heats the oil in pipe 11. Cook20 on exhaust-pipe 19 is slightly-opened, so that a constant supply offresh steam will enter pipe 16 and circulate around the oilpipe. As workvaries, the steam-pressure in the boiler varies, and this causes a wasteof fuel unless the quantity thereof is regulated.

In my burner I automatically regulate the supply of both steam and oilby the steampressure in the boiler. To accomplish this, I connect pipe63 with pipe 26. Pipe63 connects with valve-chamber 64, in which ismounted hollow valve 65, to the upper end of which is attached stem 66of regulating-piston 67, which piston is mounted in chamber 68, having acasing 68. Piston 67 has an upwardly-extending stem 69, the upper end ofwhich is seated in guide-plug 70, which is held spring-pressed by spring71, the tension of which is regulated by screw 72. Piston 67 is cut awayat its bottom, as shown in Fig. 4, but the cut-away portions are notconnected. In the lower portion of piston-chamber 68 is exhaust-port 73,while oppositely disposed thereto is supply-port 74, which is connectedby pipe 75 with the regulating-valve chamber 76, having casing 76, inwhich is seated Valve 77, held normally spring-pressed on its seat byspring 78, the tension of which is regulated by screw 79. Opening intovalvechamber 76 below valve 77 is steam-supply pipe 80, which runs toand connects with the steam space in the boiler. (Not shown.)Valve-chamber 64 (see Fig. 5) is connected by pipe 81 with exhaust-pipe19. Itis also in communication with the top and bottom of piston-chamber82 through ports 83 and 84. In this chamber is mounted the steam and'valve regulating piston 85, having stem 86, which is connected by anadjustable link 87 with lever 29. Now when the pressure rises above thepressure required to perform the necessary work it exerts a pressure onvalve 77 great enough to raise it 06 its seat, which permits the steamto pass into piston-chamber 68 and raise piston 67 against the pressureof spring 71, which causes stem 66 to raise valve to cover port 83 anduncover port 84. The steam then passes through port 84 intopiston-chamber 82 below piston 85. The upper portion of thepiston-chamber eX- hausts through exhaust-pipe 81, and the piston risesand through connecting parts operates both the steam and oil valves toout 01f the supply of both to the burner-tip, and thus reduce the amountof fuel burned, which soon causes such a reduction of steam-pressure inthe boilers that the pressure of spring 78 reseats valve 77. The steamin pistonchamber exhausts through port 73 when spring 71 pushes piston67 to its seat, which returns valve 65 to its normal position, whichpermits the steam in the lower part of piston chamber to exhaust and thesteam-pressure To be applied on the top of the piston to return it toits normal position and through connecting parts to return the oil andsteam valves to their normal position. Pipes 17 and 18 are adj ustablyconnected together by the improved coupling, (shown in detail in Fig.9,) which provides, with coupling 6, a ready means for connecting anddisconnecting the burner from the oil and steam pipes. hen it is desiredto blow out the oil-passage lead ing to the tip and the oil-conduits inthe tip with steam, the steam by-pass is opened and cut-off cock 4 isclosed. At the same time the strainer can be cleaned by steam by openingcut-oil cock 5.
